COUPLING.

SPECIFICATION forming art of Letters Patent No. 755,652, dated March 29,1904.

Application filed April 2, 1903. Serial No. 150,768. (No model.) I

To all whom it may concern:

Be it known that I, DAVID GREENBURY, a subject of the King of the UnitedKingdom of Great Britain and Ireland, and a resident'of Morayfield, inthe State of Queensland, Commonwealth of Australia, have inventedcertain new and useful Improvements in Automatic Couplings forRallwayWagons and Carriages,

of releasing-link; Fig. 3, an end view ofcoupling-hook andreleasing-link and couplinglink; Fig. 4, a plan of coupling hooks andlinks with wagons coupled together; Fig. 5, a side elevation of wagonscoupled together. Fig. 6 shows coupling thrown out of action; Fig. 7, anend View of wagon, showing chains connecting to releasing-links.

The reference-letters indicate like parts in all figures.

A is a draw-bar pivoted to cross-tie on underframe of wagon, as shown inFigs. 4 and 5, and provided with spring at end thereof connected nearthe shoulder by tie-rod B to bogie of wagon, which controls the positionof the draw-bar and insures the meeting of the drawbar with the oppositelink when coupling on a curve. Forming an integral part of the draw-barare ears A, between which is secured by bolt and nut coupling-link C,the link pivoting on the bolt. Also forming an integral part of thedraw-bar is a hook A with sloping end, acting as an inclined plane forthe coupling-link on end of other draw-bar.

To the end of the coupling-hook A is pivoted a releasing-link D,attached to which is a chain E, leading through a staple F onside ofcoupling-hook, thence branched and carried over pulleys on end of wagonto the sides thereof, and at the end of each branch of the chain is aring E, which on uncoupling the 'fall over, the releasing-link D isdrawn forward by the weight of the coupling-link, and

the wagons or carriages are automatically coupled together. To uncouple,the chain E is pulled down from either side of the Wagon or carriage,when the releasing-link D draws the coupling-link from the end of thehook, allowing it to slide up the inclined plane formed by the link Dwhen the coupling-link disengages itself from the hook.

To hold the parts in position to preventcoupling, one ring E is engagedwith its hook G; but it may be afterward disengaged by turning the rodH, which can be done from either side of the carriage.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In improvements in automatic couplings for railway wagons orcarriages, a draw-bar having a pair of ears and an extended end forminga hook, in combination with a coupling-link pivoted between the ears,and a releasing-link pivoted to the hook, as and for the purpose setforth.

2. A draw-bar having a hook, a releasinglink pivoted thereto, achainleading from said link and branched to either side of therailway-carriage, and a ring at the end ofeach branch; in combinationwith a rod journaled across the carriage, and hooks secured thereto inparallelism near its extremities, as and for the purpose set forth.

3. A draw-bar having short cars at one side and a long hook at theother, a coupling-link pivoted to the ears, and a releasing-link pivotedto the hook and adapted to swing across I simultaneously from eitherside of the car- IO its throat to disengage the companion coupriage, asand for the purpose set forth. ling-link therefrom; in combination Witha In Witness whereof I have hereunto set my chain leading from the lowerpogti? of thg hand in presence of tWo Witnesses.
